4.5 Counter
The device features one counter module per port.
A counter module consists of 2 separate counters:
Main counter: The main counter counts the rising edges of the filtered digital input signals. The
main counter has a value range that is defined by a threshold value. If the value range of the main
counter is exceeded or not reached, an overflow or underflow signal is sent to the batch counter.
Batch counter: The batch counter counts the overflow or underflow signals of the main counter.

Counter module
A counter module can be operated in different operating modes. The following operating modes are
available.
4.5.1 Counter mode CTU
In CTU (Count Up) mode, the counter module operates as an up counter with overflow detection and
overflow counter.
Behaviour:
The initial value of the main counter is m = 0. The initial value of the batch counter is b = 0. The
main counter has a threshold value CT. The batch counter has a threshold value CTb.
Remote I/O module 16 DI AL4022
11
If the counter module detects a positive edge at pin 4 of the port, the value of the main counter is
incremented (m = m+1).
If the main counter reaches the threshold value CT (m = CT), the counter value is reset (m = 0).
Due to the overflow detection, the value of the batch counter is incremented (b = b+1).
If the batch counter reaches the threshold value CTb (b = CTb), the counter value is reset (b = 0).

Batch Counter
4.5.2 Counter mode CTD
In CTD (Count Down) mode, the counter module operates as a down counter with underflow detection
and underflow counting.
Behaviour:
The initial value of the main counter is m = 0. The initial value of the batch counter is b = 0. The
main counter has a threshold value CT. The batch counter has a threshold value CTb.
The first time a positive edge is detected at pin 4, the value of the main counter is set to the
threshold value CT-1 (m = CT-1). At the same time, the value of the batch counter is set to the
threshold value CTb-1 (b = CTb-1).
If the counter module detects a positive edge at pin 4 of the port, the value of the main counter is
decremented (m = m-1).
If the main counter falls below 0, the counter value is reset to the threshold value (m = CT-1). Due
to the underflow detection, the value of the batch counter is decremented (b = b-1).
If the batch counter falls below 0, the counter value is reset to the threshold value (b = CTb-1).

4.5.3 Counter mode CTUD
In CTUD (Count Up Down) mode, the counter operates as a simultaneous up and down counter with
overflow and underflow detection.
Behaviour:
The initial value of the main counter is m = 0. The initial value of the batch counter is b = 0. The
main counter has a threshold value CT. The batch counter has a threshold value CTb.
If the counter module detects a positive edge at pin 4 of the port, the value of the main counter is
incremented (m = m+1).
If the counter module detects a positive edge at pin 2 of the port, the value of the main counter is
decremented (m = m-1).
AL4022 Remote I/O module 16 DI
12
If the counter module simultaneously detects a positive edge at pin 4 and pin 2 of the port, the
counter value of the main counter does not change.
If the main counter reaches the threshold value CT (m = CT), the counter value is reset (m = 0).
Due to the overflow detection, the value of the batch counter is incremented (b = b+1).
If the main counter falls below 0, the counter value is reset to the threshold value (m = CT-1). Due
to the underflow detection, the value of the batch counter is decremented (b = b-1).
If the batch counter reaches the threshold value CTb (b = CTb), the counter value is reset (b = 0).
If the batch counter falls below 0, the counter value is reset to the threshold value (b = CTb-1).

4.5.4 Counter mode CTDIR
In CTDIR (Count Direction) mode, the counter module operates either as an up counter with overflow
detection or as a down counter with underflow detection. The counting direction can be set.
Behaviour:
The initial value of the main counter is m = 0. The initial value of the batch counter is b = 0. The
main counter has a threshold value CT. The batch counter has a threshold value CTb.
The user can determine the counting direction. The counter module initially operates as an up
counter with overflow detection.
If the counter module detects a positive edge at pin 4 of the port and the counting direction of the
port is set to “up”, the value of the main counter is incremented (m = m+1).
If the main counter reaches the threshold value CT (m = CT), the counter value is reset (m = 0).
Due to the overflow detection, the value of the batch counter is incremented (b = b+1).
If the batch counter reaches the threshold value CTb (b = CTb), the counter value is reset (b = 0).
If the counter module detects a positive edge at pin 4 of the port and the counting direction at pin 2
of the port is set to “down”, the value of the main counter is decremented (m = m-1).
If the main counter falls below 0, the counter value is reset to the threshold value (m = CT-1). Due
to the underflow detection, the value of the batch counter is decremented (b = b-1).
If the batch counter falls below 0, the counter value is reset to the threshold value (b = CTb-1).

Port X31 has an inrush current limitation.
uDisconnect power.
uConnect the device via port X31 to 24VDC (20…30V SELV/PELV).
uFor connection, use an L-coded M12 connector (with at least protection rating: IP65 / IP66 / IP67).
uTighten the cable sockets according to the torque specifications indicated by the cable vendor.
Maximum permissible tightening torque: 0.8Nm
uObserve the derating behaviour of the device (Ò Derating behaviour/17).
